Yup.

Doesn't work very well on lifters that have gunk in them. Which is Why you are trying to take them apart.. to clean them !

Kenapa?

collapsed lifters will not bend the valves;

Thank you for confirming that they are primed when new. I am rebuilding the valve lash adjusters on my v6 2.8 30v as well, decided to just take them apart and clean the gunk out and replace the ball bearing check valve while I was at it. The ball bearing had the slightest wear on the edge where it seals and I decided to err on the safe side and just replace the balls.

ticking noise in hydraulic lifters comes from a weak spring or a lifter cant hold the oil in side it self when the camshaft push it to press the valve.

​@@miragairjet7436 thanks for your reply. In the meantime I found my answear already :) you can actually disassembly the lifters, clean them and see if you can make them work again. You can take a set of rigged pliers and pull out the center part and work from there or just simply smash the open side against a solid piece of wood and it will drop out on its own. Regardless if new out of the box or used if you can then test them all. Just put some oil into the lifter body (submerge in oil and press repeatedly or use a syringe to fill through the hole or whatever else you want to try), start pressing and see what happens. If it stays rock solid and no oil comes out then that lifter is off. If it is spongy and soft to compress then that lifter is off too. A good lifter is the one where you put some of your upper body weight on it and there is a small ammount of oil dripping out of the hole. That was the answer I was originally looking for and I found it but elsewhere. Didn't know about that until recently but this info came from a Porsche owner who does all his maintenance himself. Hope you found this usefull and can benefit from this one day :)

thanks for the info

@@_J.P._ thanks a lot man , You have the convincing answer 👌

Thanks for the tip! Thanks for watching!

Will try that! I have like 19 lifters which are completely solid and about 5 which work like they should. Placed them in my supersonic cleaner filled with ATF at 70 degrees celsius and that didn´t do much. Went for Diesel now and will let them soak. There was a bunch of nastyness coming out of the ones that still work.

I tried heat.

Heat them up real hot. Wear good quality thick gloves (leather if possible). Grab the plunger with a small water pump pliers and pull. It comes apart after a few attempts. Did all of mine (16) that way. Difficult job with stubborn, seized lifters but very possible. Must have loads of patience & determination..

@@alexbuckingham7854 Or maintain a box full of DOMESTICALLY SOURCED lifters - That way they can't be seized... It's a tax-joke... >_;

No. New lifters do not need bleeding.

You should empty them, or you may have open valves and no compression. Real difficult to get them drained and compression back, once installed.

@@Jovemdaluta somebody says you should bleed them, and others say you should not. so where is the truth. we are talking about new lifters.

@@MenTallisT_96 well i installed a new set without even looking at them. Bent 5 exhaust valves after firing it up. So , now, i always bleed and check movement of each new/used lifter.

@@Jovemdaluta shit, thx
